On branches of Tilia Americana, Helderberg Mts., N. Y. (Peck). 

 The conidial stage {Cryptospoi-ium TiUm) has conidia fusoid, 

 acute, straight or curved, hyaline, 40-50 x 6^-10 //. 



Cr. femoralis, (Pk.)

Cryptospora femoralis, Sacc. Syll. 4117. 



Valsa i Cryptospora) femoralis, Cke. Syn. 1944. 



Pustules small. Perithecia few, nestling in the inner bark. Osti- 

 ola few, short, black, erumpent through small and mostly transverse 

 chinks in the bark, crowded or scattered. Asci lanceolate. Sporidia 

 crowded, elongated, sublinear, straight or slightly flexuous, obtuse, 

 slightly thickened at the ends, 35-75 ji long. 



' On dead alder limbs, Albany, N. Y. (Peck), and California 

 (Harkness). 



Closely related to Cr. svffusa, but the sporidia are thickened at 

 the ends. The perithecia adhere to the epidermis and are torn away 

 with it.

Perithecia 3-8, subcircinate, buried in the unaltered inner bark, 

 of medium size, pale, necks convergent and erumpent through the 

 slightly raised epidermis in stout, black, rough ostiola covered at 

 first with white or light-cotored grumous matter appearing like an 

 efflorescence of the bark, and sometimes remaining as an obscure white 

 ring around the ostiola. Asci obloDg-clavate, p. sp, 75-80 x 8-10 /i, 

 stipitate and imperfectly paraphysate. Sporidia subfasciculate, 8 in an 

 ascus, cylindrical, multinucleate, becoming 3-7-septate, 56 x 5 n 

 (sec. PL). 



On dead limbs of Castanea, New York, New Jersey and Penn- 

 sylvania. 



The pei'ithecia arc of about the same color as in Diaporthe 

 leiphcBmia. We do not find the sjioridia as large as stated by Peck: 

 only about 35-45 x 3-3f /i. 



Cr. tomentella, (Pk.) 



Valsa tomentella, Pk. 35th Rep. p. 144,

Perithecia 4-8, subcircinate, nestling in the inner bark, black, 

 clothed below with a whitish tomentum, disk lanceolate, whitish or
